On Subject-Predicate Parenthesis

Subject-predicate parenthesis is very important in the interpretation of discourse and for the communication force. Relatively flexible in syntactical position, it will exert little impact on the sentence semantic if the structure is removed from the sentence.Subject-predicate parenthesis is mainly formalized as S+VP, with only limited personal pronouns, one interrogative pronoun, several imaginary nouns, few patient subjects as well as"VP/SP de"structure acting as its subject. The predicate has lost the distinguishing characteristics of verbs and is seen the tendency or clue of grammaticalisation. The whole structure is thus in the progress of wordization.Generally, subject-predicate parentheses are classified into 6 major categories: personal pronoun + observation verbs, pronouns + speculation verbs, personal pronoun + oral utterance verbs, pronouns + knowing verbs and pronouns + listening verbs. Based on these 6 categories, this paper conducts an analysis of the implication function, discourse function and text function of subject-predicate parenthesis.Subject-predicate parenthesis is featured by grammaticalisation and subjectivisation. In terms of its grammaticalisation, this paper reconstructed the development of"kan"from a verb meaning"look with eyes"to a discourse marker, then we further analyzed the subjectivisation features of subject-predicate parenthesis, holding that the final subject of subject-predicate parenthesis is, no matter it is the orator in the higher layer (the whole book) or the speaker in the lower layer (a piece of utterance), dominant or recessive, the first person in nature. The semantic of subject-predicate parenthesis is characterized by subjectivity and its form by subjectivisation.For the convenience of research, this paper does not discuss"VP/SP de"structure and the recessive form of subject-predicate parenthesis, which will be explored later on in future relevant findings.
